Ulnar nerve compression at the elbow, commonly known as cubital tunnel syndrome, can cause numbness, tingling, and weakness in the hand and fingers. The ulnar nerve runs along the inner side of the elbow, where it can become compressed by surrounding tissues or irritated through repetitive bending, prolonged pressure, or previous injury. Symptoms may include discomfort at the elbow, reduced grip strength, difficulty with fine motor tasks, and changes in sensation in the ring and little fingers. When symptoms persist despite non-surgical treatment, nerve release surgery may be recommended to relieve pressure and prevent long-term nerve damage.
At One Orthopaedics, we provide advanced diagnosis and nerve release surgery for patients across Guildford and Surrey, using techniques tailored to the severity and specific pattern of compression. Early intervention can prevent further deterioration, improve symptoms, and support a return to normal hand and arm function.
What is nerve release?
Nerve release surgery reduces pressure on the ulnar nerve by creating more space or repositioning the nerve to relieve irritation. Depending on individual needs, the procedure may involve:
- Simple decompression: Freeing the nerve by releasing tight tissue around it.
- Medial epicondylectomy: Removing a small part of bone to prevent irritation.
- Ulnar nerve transposition: Moving the nerve to a safer position in front of the elbow.
The goal is to reduce pain, improve sensation, and prevent weakness or muscle wasting.
Who Is It Suitable For?
Nerve release surgery may be recommended for individuals who:
- Experience numbness or tingling in the ring and little fingers
- Have weakness or reduced hand coordination
- Have symptoms that worsen at night or during elbow bending
- Have muscle wasting or marked sensory changes
- Have not improved with splinting, physiotherapy, or activity modification
- Require reliable nerve function for work or daily tasks
A consultant confirms diagnosis using clinical examination and, when necessary, nerve conduction studies.
How the Procedure Works
The procedure is performed under general or regional anaesthetic. The surgeon:
- Makes a small incision along the inner elbow
- Identifies and examines the ulnar nerve
- Releases tight structures compressing the nerve
- Repositions the nerve if required (transposition)
- Ensures the nerve glides freely during elbow movement
The aim is to relieve pressure and support natural nerve healing.
Recovery and Rehabilitation
Recovery varies depending on the type of nerve release. Most patients can move the elbow shortly after surgery. Early rehabilitation focuses on preventing stiffness and strengthening the forearm and hand muscles.
Recovery generally includes:
- Wound care and swelling management
- Early gentle movement exercises
- Gradual strengthening of hand and forearm muscles
- Avoidance of prolonged elbow bending during early healing
- Return to work depending on symptom resolution and job demands
Nerve recovery is gradual and may continue for several months as sensation and strength improve.
Before and After Treatment
Before treatment, individuals may experience numbness or tingling in the fingers, reduced hand strength, difficulty gripping objects, elbow discomfort, and nighttime symptoms that disturb sleep.
After treatment, nerve release surgery aims to improve sensation, reduce discomfort, and prevent further nerve deterioration. Many patients regain improved strength and function with time and appropriate rehabilitation.
